Auth library for PostgreSQL database

[eluser]kamik[/eluser]
Hi,
I am new to CodeIgniter, I am looking for some library like AU or Redux but for Postgres.

I need basic Auth methods (not for blog or anything similar=no captcha, no email activation and etc., just log in, log out, create user, drop user, who logged ...) and if there is done basic backend it will by fantastic.


Best regards
